FIELD OF THE INVENTION

The present invention relates to computer systems and more particularly, to a data analysis processor configured for processing and/or analyzing a vector based on OLAP data.

BACKGROUND OF THE INVENTION

Online analytical processing or OLAP is a technique in business intelligence applications and comprises providing answers to analytical queries that are multidimensional in nature. Examples of OLAP applications include business reporting for sales, marketing, management reporting, business process management, budgeting and forecasting, financial reporting and the like.

Databases configured for OLAP applications typically comprise a multidimensional data model, often referred to as a “cube”. A multidimensional data model allows for complex analytical queries with rapid execution time. The cube structure comprises aspects of navigational databases and hierarchical databases.

An OLAP cube can be thought of as an extension of the two-dimensional array of a spreadsheet, and comprises dimensions. In the context of an OLAP cube, dimensions provide additional methods for analyzing data. For example, an OLAP cube can be configured to allow a company to analyze financial data by product, by time-period, by city, by type of revenue and cost, and by comparing actual data with a budget. In a further aspect, a user, for example, a financial analyst, may want to view the data in various ways, such as displaying all the cities down the page and all the products across a page. This could be for a specified period, version and type of expenditure. Having seen the data in this particular way the analyst might then immediately wish to view it in another way. The cube structure provides the capability to re-orient the display so that the data displayed now had periods across the page and type of cost down the page. Because this re-orientation involved re-summarizing very large amounts of data, this new view of the data had to be generated efficiently to avoid wasting the analyst's time, i.e. within seconds, rather than the hours a relational database and conventional report-writer might have taken.

According to another aspect, it may be desirable to analyze data in a cube on a cell or tuple basis. For example, it may be desirable to provide a delta or % change analysis on data in a cube cell by comparing that data with cube data associated with another cell.

It will be appreciated that while an OLAP cube provides a flexible and multidimensional structure data model, there remains a need in the art for improvements, such as, data applications including data acquisition and processing techniques capable of exploiting the capabilities of an OLAP cube.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

Embodiments according to the present invention are described below by way of a set of screen shots that would be displayed to a user of the system. The screen shots comprise exemplary data or information used by companies for planning, budgeting, monthly financial reporting and/or consolidation of financial results. In the context of the present description, numerical data is stored in an OLAP database, and comprises one or more cubes. Each cube comprises a structure based on dimensions and members.

The cubes and dimensions will vary from company to company. In addition, the names of dimensions within cubes can vary. For instance, a cube can have dimensions named “Accounts”, “Versions” and “Time”, and a number of other dimensions with other names. Each dimension comprises a list of members. For example, an “Organization” dimension in a cube comprises a list of departments and reporting entities for a company. The dimensions can also have a calculation structure that describes data aggregation, e.g. ‘East Region’=‘New York’ plus ‘Boston’, or a calculation structure that describes a more complex calculation, e.g. ‘Benefits’ 10% of ‘Salaries’. It will be appreciated that calculations can also be different for each company.

In the context of the present description, data is stored in an OLAP database as a single numerical value for each dimension combination. For example, if the dimensions are ‘Time’, ‘Accounts’, ‘Version’ and ‘Organization’, each of which has a member called ‘Jan08’, ‘Salaries’, ‘Plan’ and ‘Boston’ respectively, then one numeric value is stored for this combination of members. Similarly, a different number is stored in the database for ‘Feb08’, ‘Salaries’, ‘Plan’ and ‘Boston’.

Typically, data is accessed (i.e. imported) in an OLAP database at a detailed level, for example, using the ‘Time’, ‘Accounts’, ‘Version’ and ‘Organization’ dimensions (e.g. ‘Jan08’, ‘Salaries’, ‘Plan’ and ‘Boston’). The data is then processed and reported at an aggregated level to provide historical information, for example, according to the dimensions, ‘Total Year’, ‘Total Expenses’, ‘Plan’ and ‘Total Company’.

As will be described in more detail below, the present invention comprises embodiments of a processing mechanism or processor configured for taking any cell in an OLAP cube and generating a base vector for the selected cell and configuring a comparison vector associated with the base vector and performing operations on data for the base vector based on the comparison vector. The comparison parameters are configured for defining a time vector for entering data, and/or comparing time vectors, accounts, organizational groups or other entities. According to another aspect, the resulting base vector can be saved back to the cube, and made available in a report, and/or for further processing and/or analysis.

In accordance with embodiments of the present invention a system and techniques (e.g. computer-implemented processes) are described in more detail below for accessing data in an OLAP database and configuring processes or operations for comparing or analyzing the data according to one or more parameters or comparison benchmarks.

Reference is made to FIG. 1, which shows in diagrammatic form an exemplary operating environment and configuration for implementing and practising a system and processes according to embodiments of the present invention. The operating environment according to an embodiment and indicated generally by reference 100 comprises a client/server configuration. As shown, one or more clients 110, indicated individually by references 110 a, 110 b, 110 c, . . . 110 n, access a server indicated by reference 120, for example, through a network 130. The network 130 may comprise a local area network (LAN), a wide area network (WAN), the Internet or any combination thereof. As shown the server 120 interfaces with a database 140. According to an embodiment, the database 140 is configured as an OLAP database and comprises a number of cubes 142, indicated individually by references 142 a, 142 b, 142 c, 142 d, 142 e, . . . . The cubes 142 are configured with dimensions and members as described above and in further detail below. For the embodiment depicted in FIG. 1, the clients 110 are connected via the Internet indicated generally by reference 130. It will be appreciated that the method and system according to the present invention may be practised or implemented for other networks and/or configurations.

According to an embodiment, the system 100 includes a storage module indicated generally by reference 132. The storage module 132 is configured to store data process definitions, for example, as defined by a user. According to an embodiment, the storage module 132 is implemented using a relational data structure or configuration.

As shown in FIG. 1, the server 120 is configured with an application indicated generally by reference 122. According to an embodiment, the application 122 comprises a client interface module 124, a calculation engine module 126 and a data analysis module or processor (e.g. a processing mechanism configured for performing delta type analysis, i.e. a “delta processor”) 128.

The client interface module 124 is configured to provide an interface with the client machines 110. According to an embodiment, the client interface module 124 is implemented with a user interface or GUI (Graphical User Interface) which runs on each of the client machines 110 as indicated generally by reference 112. According to an embodiment, the client interface module 124 and the user interface 112 comprise logic and processes configured to provide a user with the capability to specify a processing request for data in the database 140, i.e. a process for querying structural component(s) associated with one of the cubes.

The calculation engine module 126 comprises a computer-implemented process(es) or function(s) that runs on the server 120 and performs manipulation of data in the cube 142 according to a specification, i.e. a data process specified and provided by the user through the user interface 112. According to an embodiment, the execution of a data process is independent of the specification of the data process. For example, a data process can be executed multiple times and the execution of a data process can be scheduled to run at any time. According to an embodiment, the calculation engine is configured to execute process definition(s) retrieved or returned from the storage module 134.

Embodiments of the application 122, the client interface module 124, and the calculation engine module 126 are described in co-pending U.S. patent application Ser. No. 12/059,070, which was filed on Mar. 31, 2008 and is owned by the assignee in common with the subject application. The disclosure of U.S. patent application Ser. No. 12/059,070 is hereby incorporated by this reference in its entirety.

The data analysis module or processor (i.e. “delta processor”) 128 comprises a computer-implemented process(es) or function(s) that runs on the server 120 and provides a mechanism to analyze data in any cell in the cube 142. According to an embodiment, the data analysis module 128 is implemented in the form of a software application or computer program and is stored in memory and executed to provide the functionality as described herein. According to an embodiment, the data analysis module 128 is configured to generate a base vector associated with the selected cell and execute a comparison or “Delta analysis” between the base vector and a comparison vector. According to another aspect, the data processor module 128 is configured to allow a user to change one or more values (i.e. data) in the base vector and execute the Delta analysis and store the resulting modified base vector in the cube. The operation and configuration of the data processor module 128 according to embodiments of the invention is described in more detail below with reference to the user interface and screen shots depicted in FIGS. 2 to 16.

According to an embodiment, the data analysis module 128 is configured with a graphical user interface or GUI comprising a data analysis screen or window as shown in FIG. 2 and indicated generally by reference 200. According to an embodiment, the data analysis module 128 and the data analysis screen 200 are configured to provide a user with a mechanism to look at any cell in a report screen, and according to an embodiment the data analysis module 128 is configured to provide a time vector (e.g. a default time vector) associated with the selected cell and according to another aspect, the data analysis module 128 and the data analysis screen 200 are configured to provide the user with a mechanism for defining a comparison vector and performing comparison operations between the base and comparison vectors, as will be described in more detail below.

According to an embodiment, the data analysis screen 200 is accessed or displayed in response to a data object or cell being “clicked” (e.g. a “right-click” using a mouse or other input device). For example, FIG. 3 shows a screenshot of a “Template Style” Report indicated generally by reference 300. The Template Style report 300 comprises an exemplary report for revenue streams associated with a software product line and is arranged in rows and columns as shown in FIG. 3. According to this aspect, each revenue number 310 in the report 300 comprises an active data object and corresponds to a cell or a tuple in the cube 142. For example, the revenue number for the month of “March” for the “Professional Services Revenue” comprises a data object indicated by reference 310-3 c. According to an embodiment, the data objects comprise active elements and are responsive to a user activated device, e.g. a mouse, and in response to a mouse click, the application 122 (FIG. 1) is configured to display a drop-down menu box 320 having a form as shown in FIG. 3. According to an embodiment, the drop-down menu box 320 includes a “Delta Analysis” menu item indicated by reference 330. Selecting or “clicking” the Delta Analysis menu item 330 causes the application 122 to display the data analysis screen 200 as shown in FIG. 2.

Reference is also made to FIG. 4, which shows an “Ad Hoc” style report screen indicated generally by reference 400. The Ad Hoc report screen 400 is another report style that is supported by the application 122. The Ad Hoc report screen 400 comprises financial data arranged in columns and rows and is configured to allow a user to quickly populate and modify data entries, e.g. line items. According to an embodiment, the line items in the Ad Hoc report screen 400 comprise active data objects indicated generally by reference 410. In a manner similar to the Template Style report screen 300, the data objects 410 are configured to be responsive to a user input device, e.g. a mouse, and in response to being clicked, the application is configured to display a drop-down menu box 420 having a Delta Analysis menu item 430 as shown in FIG. 4. The application is configured to display the data analysis screen 200 in response to the Delta Analysis menu item 430 being clicked or selected by the user.

Reference is made back to FIG. 2. According to an embodiment, the data analysis screen 200 comprises a menu bar 210, a tool bar 220, a “Base” vector panel 230, a “Comparison” vector panel 240, a “Time Scope” configuration panel 250 and a Data display window 270. The menu bar 210 is configured with “File” tab 212, an “Edit” tab 214, and a “View” tab 216. The tabs allow a user to switch or move between screens and the layouts of certain screens will change depending on the options selected in the other tabs, as will be described in more detail below.

As shown in FIG. 2, the tool bar 220 is configured with a “Close” button 221, a “Grid” display button 222, and a “Chart” display button 224. In “File” mode, the tool bar 220 is also configured with file management tools comprising a “Print” button 225, a “Preview” button 226 and a “Page Setup” button 228.

The Base vector panel 230 is configured to show the dimensions for the vector associated with the selected data cell. The exemplary base vector depicted in FIG. 2 comprises the following dimensions; a “Measures” dimension indicated by reference 232, an “Organization” dimension indicated by reference 234, a “Versions” dimension indicated by reference 236, and an “Accounts” dimension indicated by reference 238. According to an embodiment, each of the dimensions includes a drop-down list which lists the members associated with the dimension. For example, the Measures dimension 232 comprises a members drop-down list indicated by reference 233 with “Value” showing as the selected member; the Organization dimension 234 comprises a members drop-down list indicated by reference 235 with “NA Sales” showing as the selected member; the Versions dimension 236 comprises a members drop-down list indicated by reference 237 with “PY Actual” showing as the selected member; and the Accounts dimension 238 comprises a members drop-down list indicated by reference 239 with “Net Operating Expenses” showing as the selected member. The members drop-down list 235 for the “Organization” dimension 234 is shown in expanded form in FIG. 6 and indicated by reference 235′. As shown in FIG. 6, the members for the Organization dimension 234 comprise the following entities: “CMC”, “Corporate, “Professional Services”, “Development”, “Product Management”, “INT Channel Partners”, “Marketing”, “NA Channel Partners”, “NA Sales” (selected by mouse as indicated by reference 635), and “Total Organization”. The data analysis processor 128 is configured to read data from cells (i.e. tuples) in the cube based on the members (i.e. 233, 235, 237 or 239) selected for the Dimensions (i.e. 232, 234, 236 or 238) specified in the base vector panel 230 for example as shown in FIG. 2.

Referring back to FIG. 2, the comparison vector panel 240 is configured to select members from the dimensions associated with the comparison vector. According to an embodiment, the comparison vector is configured with the same dimensions as the base vector. For the example configuration depicted in FIG. 2, the comparison vector comprises a “Measures” dimension 242 (corresponding to the Measures dimension 232 in the base vector), an “Organization” dimension 244 (corresponding to the Organization dimension 234 in the base vector), a “Versions” dimension 246 (corresponding to the Versions dimension 236 in the base vector) and an “Accounts” dimension 248 (accessible using GUI scroll bar 249. According to an embodiment, each of the dimensions for the comparison vector includes a respective active data object that shows the selected member for the associated dimension. For the example configuration depicted in FIG. 2, the Measures dimension 242 has a selected member 243 “Same as Base” which indicates that the member is the same as the base member, i.e. the “Value” member 233. The Organization dimension 244 also has a member 245 “Same as Base” which is the same as the selected member for the corresponding base member dimension, i.e. the “NA Sales” member 235. For the Versions dimension 246, the selected member is “Plan” as indicated by the displayed data object 247.

According to an embodiment, the comparison vector 240 is populated with data according to the Version dimension 246. For the example, as depicted in FIG. 2, the Version dimension 246 is configured for the “Plan” member 247, and accordingly, the data processor module 128 populates the comparison vector (for example, row 278 in the data display window 270) with “Plan” data values, i.e. data values that were previously reviewed. According to another aspect, the comparison vector may be configured with other members 247 of the Version dimension 246, for example, “Actual” or “Forecast”.

According to an embodiment, the data analysis processor 128 is configured to extend any changes in the dimensions of the base vector 230 to the comparison vector 240 when the active data object for the corresponding dimension in the comparison vector 230 is set to “Same as Base” as described above and indicated for the Measures dimension 242 and the Organization dimension 244 in FIG. 2.

The base vector 230 includes a time dimension and according to an embodiment, the Time Scope panel 250 is configured for setting the time frame for the base vector 230 and the comparison vector 240. According to an embodiment, the time scope panel 250 includes a Base Start Period setting control 251 and an Base End Period setting control 252. According to an embodiment, the Start Period setting control 251 comprises an active text field or object 253, a go back button 254 a and a go forward button 254 b. Similarly, the End Period setting control 252 comprises an active text field or object 255, a go back button 256 a and a go forward button 256 b. The active text fields 253, 255 are configured to be responsive to a mouse click or other input device and display a list of start/end periods (e.g. months), for example, in the form of a Time Dimension select dialog box 1600 as depicted in FIG. 16. The selected start/end period is displayed in the respective active text field 253, 255. Clicking the go forward 254 b, 256 b buttons or the go back buttons 254 a, 256 a allows a user to change the selected start/end periods. In order to provide a valid comparison, the periodicity (e.g. monthly, quarterly, and yearly) for the comparison vector 240 must be the same as that for the base vector 230 as indicated by the respective text fields 253 b and 255 b. According to another aspect, the time scope panel 250 includes a time slider bar 258 for the base vector 230 and a corresponding time slider bar 260 for the comparison vector 240. As shown, the time slider bar 258 is configured with a go back button 262 a, a go forward button 262 b, and a slider control 263 for changing or modifying the time scope for the base vector 230. Similarly, the time slider bar 260 for the comparison vector 240 is configured with a go back button 264 a, a go forward button 264 b, and a slider control 265 for changing or modifying the time scope for the comparison vector 240.

According to an embodiment, the data analysis processor 128 is configured with one or more functions or software components configured to determine an initial time scope as follows:

-   -   if there is only one level in the time dimension, then the time         scope is all time members and the periodicity is that of the         single level;     -   otherwise, if the number of leaf descendants of the selected         member is 13 or less, then the time scope is from the first leaf         descendant to the last leaf descendant of the selected member         and the periodicity is the same as that of the leaf members of         the selected member;     -   otherwise, if the selected member is a leaf member and the         number of leaf members of the year containing the selected         member is 13 or less, then the time scope is the entire year         containing the selected member and the periodicity is the same         as that of the selected member;     -   otherwise, if the selected member is a leaf member, then the         time scope is the parent of the selected member and the         periodicity is the same as the selected member;     -   otherwise, the time scope is that of the selected member and the         periodicity is the same as the children of the selected member.

Referring again to FIG. 2, the data display window 270 according to an embodiment is configured to provide two types of data displays: a grid or tabular display and a chart display. The data analysis screen 200 is configured to allow a user to switch between the grid and chart displays using the “Grid” button 222 and the “Chart” button 224. For the configuration shown in FIGS. 2 and 6, the data display window 270 comprises a grid display as indicated by reference 271 with data values and other parameters arranged in rows and columns. As shown in FIG. 2, the grid display 271 comprises a “Base” row 272, a delta row or vector 274, a delta % row or vector 276, and a comparison row or vector 278.

The base row 272 corresponds to the base vector 230 and comprises columns or data cells, i.e. data values, 273 indicated individually by references 273 a, 273 b, 273 c, 273 d, . . . , which comprise a data value in a cell in the cube corresponding to the dimensions and members selected for the base vector in the base vector panel 230. The columns of the data cells 273 are configured according to the time base (i.e. time scope and/or periodicity parameters) defined in the time scope panel 250 as described in more detail below. As shown, the base row 272 also includes a “Total” column indicated by reference 275. The total column 275 comprises the total value, i.e. summed value, of the values in the data columns 273 and would also include any data columns not visible in the window 270 (i.e. accessible using a scroll bar 271). According to an embodiment, the data cells or columns 273, 275 may be altered as described in more detail below.

The delta row 274 comprises columns or data cells 277, indicated individually by references 277 a, 277 b, 277 c, 277 d, . . . , and a “Total” column indicated by reference 279. The delta row 274 corresponds to the base vector 240 and will have the same dimensions as the base vector 230. The data cells 277 and the total column 279 in the delta row 274 are editable by the user and will contain data values selected or configured for performing or executing “delta analysis” operation as described in more detail below.

The delta % row or vector 276 comprises columns or data cells 281, indicated individually by references 281 a, 281 b, 281 c, 281 d. As shown in FIG. 2, the delta % row 276 also includes and a “Total” column indicated by reference 283. According to an embodiment, the data analysis processor 128 is configured with a function or software component that calculates the relative percentage of the data in the columns 277 and 279 of the delta row 275 and the respective data in the columns 285 and 287 in the comparison row vector 278. Operation of the delta % according to embodiments of the invention is described in more detail below. According an embodiment, the data analysis processor 128 is configured with a function or software process to “spread” data entered in the Total column 283 across the data cells 281 of the delta % row 276, as described in more detail below. In a business application, the delta % values can be used, for example, as part of an analysis which is used to calculate “year-on-year” percentage cost increases or percentage variations between “Planned” (i.e. corresponding to the comparison vector row 278) and “Actual” (i.e. corresponding to the base vector row 272).

The comparison row 278 corresponds to the comparison vector 240 and comprises columns or data cells 285, indicated individually by references 285 a, 285 b, 285 c, 285 d, . . . . As shown, the comparison row 278 includes a “Total” column indicated by reference 287. The comparison row 278 has the same dimensions and time scope as the base row 272 (i.e. the base vector 230). According to an embodiment, the data analysis processor 128 is configured to apply a delta analysis comprising the difference between the respective columns in the base row 272 and the comparison row 278, and the resulting data values are shown in the respective columns 277, 279 of the delta row 274. According to an embodiment, the columns or data cells 277 of the delta row 274 are editable or modifiable, and the data analysis processor 128 is configured to calculate the change(s) in the base row 272 resulting from a change in one or more of the columns 277 of the delta row 274.
